The device comprises in a Way, a secto be used on'clarfy or supplementary chase, Within a regular printing chase, W1th othei" type, but the present device maybe used 13V itscli in'some instances althouglrnot so intended fongenerel' The body ofthe device is in the form eta rectangular case,

ancl comprises th-e'hotton'i 141', enclavalls'lfi integrelii ith the bottom, sidewalls or plates 16, ancl'transverse'fend blocks 17 secureclon the bottom 14 aini-agai'n'st the end M11915.-

cl an d away aiy impression member- 18 is disposed above the body and serves to and being The plate or ,n'iemher 18 is the device may assume inverted or other positions in various styles of prii'it'iiig presses. i The impitessi n pla'te or member 18 ispro-f vitletl at its ends with dependingshanks or" portions 19 whi ch are sli clable' in channels-- or g-rnoves 20 with which the blocks 17 are formed adjacent to the end walls 15, thereby guiding the plate 18 for up and down movement. Such movement is limited by the provision of vertical slots 21 in the shanks 19,

and stop pins or screws 22 extending through the end wal s 15 and into the blocks 17, said screws extending through the slots 21 to limit the.movemcnt of the plate 18 away from the body.

The plate 18 is raised yi-eldingly by means of coiled springs 23 confined between the plate 18 and body. the blocks 17 having recesses. or sockets 24; to receive said springs which are located near the four corners of the body. The springs 23 offer sufficient resistance in order to prevent the plate 18 from being depressed the full'amount when said, plate contacts with the soft inking rollers of the press as will hereinaftermore fully appear, although the plate 18' is compelled to yield when brought against the platen when the impression is made.

The plate 18 has a. pair of longitudinal lips 25 struck up *ardly therefrom and converging upwardly toward as another, with a longitudinal slot 26 between them. The edges of the lips 25 provide primary impression portions or bars to receive the black or other usual ink from the inking roller or rollers so as to make two parallel lines or bars on the sheet when the regular type impressions are made. It will be understood, however, that the plate 18 may carry other suitable impression portions for making regular color impressions on the sheets. As shown, the plate 18 has a downturned inarginal rim or flange 27 which strengthens and stiffens said plate, and reinforcing bars or strips 2'? are secured to the bottom surface of the plate 18 at the ends thereof to seat on the springs 23.

The secondary or contrasting color impression member 28 may be a solid line of type, individual type, a line cut, engraving, or the like, and may have suitable letters, words, numbers or other characters, and the secondary impression member 28 is accommodated by a receptacle 29 mounted in the body of the device. Said receptacle is of elongated form, as shown, and disposed longitudinahy of the body at the'longitudinal center line, and said receptacle has its lower edge portion engaging through the bottom 14L. Sa d receptacle is open at the top and bottom, in order that the member 28 may be readily inserted into the receptacle or holder 29 from the bottom, and in order that the face of sand member Wlll be exposed at the top of the device through the slot 26. The

impression member 28 is type high, so as to correspond with the regular type amongst which the device is used, a-nd the top plate or primary impression member 18 is raised by the springs 23 so that the lips or impression portions 25 are normally above'the levelor plane of the type faces. The receptacle 29 has outstanding flanges 30' at its opposite sides secured on the bottom 14c of the body, whereby said receptacle is secured rigidly to the body as a part thereof, and the impression member 28 is therefore non-movable relatively to the device, the same as the regular type, and said member 28 remains in upright position. The n'ieniber 28 any be readily withdrawn from the body through the bottom thereof when the device is removed from the printing press or the chase thereof, in order that different impression members may be used interchangeably in the receptacle 29.

The ink, pigment or other color medium for making the contrasting color impressions is supplied by a ribbon or web 30 of fabric or other material containing, by absorption or otherwise, the ink or pigment. The rib boil or web 30 extends over and across the face of the type or impression member 28, in order that the'impression by the member 28 is made through the ribbon or web, similarto the impressions made by a typewriter, excepting that the ribbon 30 of the present device remains in contact with the face of the type or impression member 28.

Provision is made for accommodating a ribbon of considerable length and for moving the ribbon so asto presentsuccessive portions thereof for making the impressions. For this purpose, parallel longitudinal shafts 31 and 82 are disposed at the opposite sides of the receptacles 29, or between said receptacle and side plates 16, longitudinally of the device, and said shafts provide drums or spools on which the ribbon is wound in reverse directions, as clearly seen in Fig; 8. The shafts may be slotted to receive the terminals of the ribbon or may have other means for receiving said terminals in order that the ribbon will be wound on said shafts. The terminals of the shafts 31 and 32 are mounted for rotation in slots 33 with which the inner sides of the blocks 17 are formed, in order to mount said shafts for rotation. Said slots extend to the ends of the blocks 17 or the opposite sides of the device in order that said shafts may be readily inserted into and removed from said slots when the side plates or walls 16 are moved so that the ribbon may he ren'ic'ved and replaced when worn out. The side plates 16 have inwardly extending lingers 34 that slide into the slots 3?) when the side plates are moved against the edges of the bottom 14- and end walls 15, thereby confining the shafts 31 and 32 between the inner ends of the slots 83 and lingers 341. The terminals of the shafts thus provide trunnions, received by the sockets formed by the inner end portions of the slots beyond the fingers 34. Vhen the side plates 16 are assembled with the blocks 17 and are held in place, such as by beingfconfined within the type of a printing press chase, the shafts 3i and will be retained 1n proper position, although said shafts are free to rotate. When the device is liberated from the printing); press. so that the side plates 16 can be renimvcd, this will pern'iit the shafts 31 and 32 to be withdrawn from the slots for inspecting or changing; the ribbon. Tension means are provided in onder to keep the ribbon 30 under tension so that it will bea with desired tension on the face of the type or impression member 28, and to also prevent the ribbon from unwinding too freely from the shafts. The tension means comprise leaf: springs 36 seated on the bottom 11, for the contact of friction disks secured on the shafts 31 and 32 adjacent tov the one block 17. The leaf springs 36 are disposed transversely below the shafts and are secured at their outer ends, as at 37. on the bottom 1 The armeciate portions of the leaf springs-are offset upwardly, as 38, and are slightly ooncaved longitudt nally for contact with the lower portion of the disks 35,112; seen in Fig. 7. Tl'xe'iilislis 35 may be readily moved over and oil the lealt'springs in inserting and removing the shafts 31 and 32, and when the shafts are inserted, the disks 35 being moved over the leaf springs will depress the portions 38 slightly so as to create the desired tension due to the frictional contact of-the leat springs 36 and edges of the disks 35. The leaf springs will also prevent the accidental dropping of the shafts 31 and 32'froin the slots 33 when the side plates 16 are removed, thereby requiring: that the shafts be with drawn with SLl'lfiClQllt force to disengage the disks from the lear" springs 86 It will be apparent that when the shafts are r0- tated, the dislzs rotate with them and the edges of the disks bearing; .on' the leaf springs will create resistance to the rotation of the shafts, thereby keeping the ribbon 30 t-rut as it is wound on one shaft and unwound from the other. The disks however, will readily roll onto and as the leaf springs when. inserting and removing the shafts. l l hen the parts are assembled, the 1621i springs contacting with the disks 35 will prevent the tree rotation of either shaft in order to prevent the ribbon from unwind ing: from either shaft and becoming loose or smelt.

iictuatii'igr i'nechanisin is provided for rotating the shafts ,81 and 32 to'move the ribbon step by step. For this purpose, ratchet wheels 39 are secured on the shafts, prefer- ,abl near these ends of the shafts opposite to the friction disks 35, and said ratchet wheels arej in reversed arrangement, "as clearly seen in Fig. 9; Hook pawls' lll are provided to alternately engage the ratchet wheels, andare pivotally suspended, as at by permitti &

ll from a tran is slidable transversely of the plate 18.

Said slide is carried by the plate in contact with the bottom surface thereot', the slide having slots 43 receiving); screws or headed studs 44-. depending; from the plate 18, there.

the slide -12 to shift transversely under the plate 18, and said slide is re ed and lowered with. said'plate. The

e 42 provided intermediate its ends with a depending arm 45, and light coiled Worse slide or carrier l2 that spring is used, which is oi L-shape, being secured at its elbow to the plate 18 the bottom surface thereol, by a screw or securing element 48, with one'arin of the spring bearing against the rim or flange 27. The other arm or the spring 4;? has a cam lug or bend L9 to engage a lug 50 on one side of the slide .2. The lugs 49 and 50 cooperate with one another, with the lug l9 bearing against the side of: the slide under spring pressure; The lug 50 moves to opposite sides of the lug 1 9 and when suilicient pressure is applied to the slide to move the lug 5O slightly beyond intermediate position the pressure of the spring 17 will move the slide 4-2 completely in. the direction in which it is started. Thus. the sli .e 42 will snap beyond intermediate position in either direction, so that the reversal of the slide and actuating; mechanism will take place with a sharp quick movement.

j The reversing lllQ-ZLHS includes a pair of tripping levers 51 pivoted, as at 52, to the inner side of the block 1'? adjacent to which the ratchet wheels 39 are located, and said levers 51 depend from the pivots 52 and have inwardly extending lugs til at their lower ends disposed at the opposite sides of the arm 45. A ligl'rt coiled spring hil is disposed between the levers 51 in order to swing same apart, and when either lever 51 is swung inwardly the lug fi l thereof will contact with the arm 45 to move the slide 4-2 in the same direction. The levers 51 have the cams or cam arms 63st their upper ends which diverge apart upwardly, and a transverse piece 67 is riveted or otherwise secured to the plate 18 at the bottom surface pend lugs 6'7 cooperable with the e ins under certain conditions, as will hereinatter moreinlly appear, so tha when one of: t ie cot above the levers 51 and has (lee the top plate 18 will result in such lever being; swung further toward the opposite lever by'thexprcssurc which forces the top plate idown.

Actuating levers 55 are disposed on the bottom 14-, being formed from plates of sheet metal, as shown, and said levers 55 have notches 57 engaging under screws orheaded studs 56 secured on the bottom 14 at the oppositesides of the receptacle 29 near that end' f the recoptacleadjaccnt to the ratchet wheels 39. lhe screws or studs 57 retain the lovers 55 in position on the bottom 14. Said levels 55 have arms 59 projecting toward the opposite end of the body and provided with upstanding portions 60 disposed the opposite sides of the two shafts 31 and 32 to e moved toward the side plates 16 when the ribbon is wound on said shafts. -The levers 55 have fulcrum or rocker portions 58 to bear against the side plates 16, and said levers have arms 61 projecting toward the levers 51 and provided with upstandinglngs 62 at the opposite sides of the lugs 54, so that when either lever 55 is swung by the outward movement of the portion 60 thereof, the arm 61 of the lever is swung away from the corresponding side plate 16 to swing the corresponding lever 51 toward the opposite side plate or wall.

A transverse guard or shield 64 is secured to and across the end of the receptacle 29 adjacent to the ratchet wheels 39 to prevent the ribbon 30 from shifting longitudinally so as'to become entangled with the pawls and ratchet wheels. The bottom 14: has an open inn 65 to receive the arm 15 when the plate or impression member 18 is depressed.

The operation of the device is as follows:

lVhenthe ink is being applied to the type,

the lips or portions 25 contacting with the inking roller or rollers will receive ink therefrom, and the springs 23, although permitting the top plate 18 to yield, are of sufficient strength to prevent the full depression of the top plate 18, thereby keeping the inking roller out of contact with the ribbon 30.

In other words, the inking roller being of.

soft rubber or yield-able compositionwill be forced away from the face of the member 28 and portion of the ribbon thereon, thereby maintaining a clearance between the inking roller of the printing press and the-second ary or contrasting color printing means. Vhen the lips or bars 25 contact with the sheet laying against the platen of the press, the platen cannot yield, so that the top plate 18 is depressed or forced to yield so that the edges of the lips or portions 25 move flush with or into the same'plane as the faces of the type includin the face of the type or secondary impression member 28. The member 28 Will'make an impression on the sheet through the' ribbon 30, thereby printing the characters of the n'iember '28 on the sheet between the lines or barsprinted by the lips 25. 'Said lines Or bars will be printed in the black'or regular ink used for the regular printing, while the characters printed by the member 28 will be of the color of the ribbon 30, which may be red, blue or other color in contrast to the color of the ink supplied by the inking roller of, the press. It is also possible to have the ribbon provided with strips or hands of different colors, so that the impression made by themember 98 may be of one or more colors;

The ribbon 3Q is moved step by step by the full. depression of the plate 18, when the impressionsrare made. Thus, when said plate 18 is depressed thefull amount, the pawls 40 are similarly depressed, and that pawl which engages the corresponding ratchet wheel will catch under the next tooth of the ratchet wheel so that when the plate 18 is released from the platen of the press. the springs 23 raising the plate 18 will result in said ratchet wheel being turned one step. This winds the ribbon slightly on the corresponding winding shaft. In this way, when the plate 18 is depressed successively the ratchet device will wind the ribbon on one winding shaft, so as to feed the ribbon step by step across the type or impression member 28. This presents successive portions of the rib bon for making the impressions, so that the impressions will be uniform. As shown in Figs. 8 and 9, theright hand pawl 10 engages the ratchet wheel 39 of the shaft 32, so that the ribbon is being wound on the shaft 32, said shaft being turned one step for each full depression of the plate 18 when making aprinting,- impression. When one shaft or spool becomes filled with the ribbon, the ratchet device is reversed so as to reverse the movement of the ribbon and wind it on the other shaft. Thus, as shown in the drawings the ribbon is being wound 1 on the shaft 32, with the slide 12 in the righthand position, as seen in Fig. 9, the lug; 50 being at theright of the lug 4190f the spring 47. As the ribbon is wound on the shaft 32 the diameter of the wound portion of the ribbon on said shaft increases, thereby pushing the portion 60 of the corresponding lever 55 outwardly toward the respective side plate 16, and swinging said lever 55 to move the arm 61 thereof toward the opposite side. The right-hand lever 51 (Fig. 9) will therefore be moved towardthe left so that its cam 63 will be moved toward the right, the cams 63 being normally between the lugs 67 so as not to be in the-pathsof movement thereof. The right hand lever 51 is therefore moved gradually as the shaft or spool 32 becomes filled with the ribbon, and when a sutlicient the right.

51 Willbe moved under the right-hand lug 67,,so that the next timegthat the plate 18 is depressed, the right hand dug (57 Will, engage the cam 63 of their htrhand lever 51. Said lug will therefore the right-hand lever 51. in the same ,direc in Fig. 10 This movement of thelever 51 is sharp and the inoveme rtot'the lever under sutlicient to reverse the slide'tl. V I movement otthe rightrhand lever '51. toward thelelt will result in Ethelug 54c- 0i: said lever contacting with the arm'efiand n ov, 1 g said arm toward the left, .so that the lug e O of the slide will snap past the dug 4:9 of-the spring 47. This will revei se thef slide ,42 and ratchet devices during one depression ofthe plate 1.8.

the right-hand pawl having been removed from the "ratchet wheel of the shaft 82. Now, the depression ofthe plate 18 wi'llresuit iirthe shaft 31 beingrotated to Wind the ribbon thereon, and whenthe shaft or spool 31 becomes full the left-hand (Fig.9) levers 55 and 51 will shift the slide A2 to This reversal takes place auton'iaticallywheneither-shaft orv spool becomes full of ribbon.

The screws or threaded studs 57 hold the levers 55 on the bottom 14 and prevent said levers from being displaced longitudinally,

but the levers, when moved by the ribbon on the shafts oi-spools, rock or oscillate on the rockers 58 as iulcrums, said rocker-s bearing against the side plates 16. WVhen the side plates 16,:1re removed, the levers 55 may be readily withdrawn, to pmtmit'the shafts or spools 31 and 32 to .be removed for inspecting the device or replacing the ribbon.
